TianTian is a Chinese (HSK) flashcard web app that runs in your phone browser, operated by the TianTian team. By using it you agree to these terms.
The free tier includes a limited set of words in each level. Premium unlocks all levels and all words with a single subscription. Premium content is available only while your subscription or plan is active.
Payments are processed by Stripe. Monthly and yearly subscriptions renew automatically until you cancel. You can cancel or update your payment method at any time through the “Manage subscription” portal in the app (log in, then open Manage subscription). Cancelling stops future renewals; you keep access until the end of the period you already paid for. Prices are shown at checkout.
The lifetime plan gives access for as long as the product exists. It is not a promise that TianTian will operate forever. The founder plan is an early-supporter offer; its price and terms are those shown at checkout when you buy.

Use TianTian for personal learning. Do not copy, scrape, resell or redistribute the content, share your login, bypass the Premium access controls, or interfere with the service.
Mandarin audio is computer-generated and may not sound like a native speaker in every case. We work to keep the content accurate but do not guarantee it is error-free.
TianTian is a study aid. We do not guarantee any exam result, and we are not affiliated with or endorsed by the official HSK organisers.
The service is provided “as is”. To the extent permitted by law, the TianTian team is not liable for indirect or consequential losses, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing here limits rights you have under mandatory consumer law.
These terms are governed by the laws of Brazil.
We may change these terms or the service. The date at the top shows the latest version; continuing to use TianTian means you accept the update.
